Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fitness equipment, and in particular to a rowing machine. Background Technology
[0002] Rowing is one of the main exercises for strengthening back muscles and is a must-do exercise for many fitness and sports enthusiasts.
[0003] Currently, most barbell rowing exercises on the market are performed using a regular barbell. Barbell rows require a certain level of skill; beginners or those without prior experience may struggle to perform effectively if they don't fully grasp the movement. Specifically, barbell rows require the barbell to be close to the thighs, and controlling the distance can be difficult. Too much distance puts pressure on the lower back; too little distance can cause chafing. Prolonged barbell rowing can also inhibit leg hair growth or cause hair loss. When performing rowing with dumbbells, even force application with both hands is required, making coordinated movement challenging. Maintaining good control of the distance between the dumbbells and the body is also crucial; otherwise, there is a risk of chafing. Utility Model Content
[0004] Therefore, it is necessary to provide a rowing device to solve the above-mentioned technical problems.

[0024] refer to Figures 1 to 3 This application provides a rowing device, which includes a support frame 1 and a bell assembly 2. The support frame 1 includes a main body 11 and bell support arms 12. The main body 11 is arc-shaped. The number of bell support arms 12 is at least two. The at least two bell support arms 12 are symmetrically arranged on the outer side of the main body 11. The main body 11 and the bell support arms 12 are on the same plane. Each bell support arm 12 is provided with the bell assembly 2.
[0025] This application provides a rowing machine. By setting the main body 11 in an arc shape, at least two weight plate support arms 12 are symmetrically arranged on the outer side of the main body 11, and the weight plate assembly 2 is arranged on the weight plate support arms 12. During exercise, the human body will be at the geometric center of the rowing machine to perform the lifting action. The human body and the rowing machine always maintain a certain spatial distance, which can generate force evenly and smoothly during exercise. There is no need for the legs to be in close contact with the machine, which can prevent the machine from damaging the skin of the legs.
[0026] Furthermore, the rowing machine of this application allows the exerciser to exert force evenly throughout their entire body, preventing injury or skin damage caused by the immense pressure concentrated on a single part of the body, and making operation simpler and safer. The rowing machine of this application can also extend some exercises that cannot be performed with barbells and dumbbells, such as raising the machine forward with both hands, which effectively trains the shoulders, arms, and core strength; and raising the machine backward with both hands, which effectively trains the biceps and triceps muscles.
[0027] refer to Figure 1 and Figure 2 The axial direction of the bell support arm 12 is perpendicular to the tangent direction of the connection point between the bell support arm 12 and the main body 11, which facilitates the even application of force by the human body.
[0028] Specifically, the weight plate support arm 12 extends from one end of the main body 11 away from the center of the arc shape in a direction away from the center of the arc shape. This is because when a person is exercising, standing at the geometric center of the equipment can prevent the weight plate support arm 12 from extending into the main body 11 and interfering with the exercise, thus affecting the exercise.
[0029] Specifically, the main body 11 and the bell support arm 12 are integrally formed, which can enhance structural stability.
[0030] Specifically, the length of the main body 11 is greater than the length of the weight plate support arm 12 to prevent the weight plate support arm 12 from being too long and affecting the force exertion during exercise. Furthermore, the length of the weight plate support arm 12 is less than or equal to one-third of the length of the main body 11 and greater than or equal to one-quarter of the length of the main body 11.
[0031] Specifically, the central angle of the main body 11 is greater than or equal to 150 degrees and less than or equal to 90 degrees. In this embodiment, the central angle of the main body 11 is 120 degrees.
[0032] Specifically, the distance between the highest and lowest points of the main body 11 is designed to be greater than the thickness of the exerciser's body, so that the exerciser can be positioned at the geometric center of the boat changer. Furthermore, the distance between the highest and lowest points of the main body 11 is greater than 20cm.
[0033] In this embodiment, there are three weight plate support arms 12. Two weight plate support arms 12 are located at both ends of the main body 11, and the other weight plate support arm 12 is located in the middle of the main body 11. This arrangement can improve the overall training effect of various parts of the human body during exercise.
[0034] In other embodiments, the number of bell support arms 12 is greater than or equal to four, and the multiple bell support arms 12 are symmetrically and evenly arranged on the outer side of the main body 11.
[0035] refer to Figure 1 and Figure 3 The weight plate assembly 2 includes a barbell plate 21 and a limiting component 22. The barbell plate 21 is sleeved on the weight plate support arm 12, and the limiting component 22 is disposed on the weight plate support arm 12. The limiting component 22 is used to limit and fix the barbell plate 21.
[0036] Specifically, the bell assembly 2 is located at one end of the bell support arm 12 near the main body 11.
[0037] refer to Figures 1 to 3 The limiting component 22 includes a limiting member 23 and a barbell lock 24. The limiting member 23 and the barbell lock 24 are sleeved on the barbell support arm 12. The barbell plate 21 is disposed between the limiting member 23 and the barbell lock 24. The limiting member 23 and the barbell lock 24 cooperate to limit and fix the barbell plate 21.
[0038] Specifically, there is at least one barbell plate 21. In actual use, the number of barbell plates 21 can be increased or decreased to adapt to different training needs.
[0039] Specifically, the limiting member 23 and the support frame 1 are integrated. By having the limiting member 23 abut against one side of the barbell plate 21 and the plate lock 24 abut against the other side of the barbell plate 21, the barbell plate 21 can be prevented from slipping off the plate support arm 12.
[0040] This application achieves highly even force distribution by positioning the human body at the geometric center of the rowing machine and maintaining a constant spatial distance from it, while gripping the main body 11. No single part of the body bears excessive pressure, and the legs do not need to be in close contact with the machine, preventing damage to the leg skin. In short, this rowing machine is safer, more convenient, and more efficient to operate.
[0041] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
